Ciprofloxacin reduces the stimulation of prostaglandin E2 output by interleukin-1 in human tendon-derived cells [PDF]

, 2003
Fluoroquinolone antibiotics such as ciprofloxacin can induce tendon pathology and have various effects on tendon-derived cells in culture. We are investigating whether ciprofloxacin modifies signalling responses in tendon cells.

Diversity, transfer potential, and transcriptional activity of virus‐carried antibiotic resistance genes in global estuaries

iMetaOmics, EarlyView.
Estuaries are vital hotspots for antibiotic resistance genes (ARGs) due to substantial antibiotic pollution. Although viruses have been proposed as key reservoirs and important disseminators of ARGs in environments, their contribution to the estuarine antibiotic resistome remains largely unknown.

Analytical profiling of mutations in quinolone resistance determining region of gyrA gene among UPEC

PLoS ONE, 2018
Mutations in gyrA are the primary cause of quinolone resistance encountered in gram-negative clinical isolates. The prospect of this work was to analyze the role of gyrA mutations in eliciting high quinolone resistance in uropathogenic E.coli (UPEC ...

Mortality after broad‐ versus narrow‐spectrum antibiotic treatment for patients with nursing and healthcare‐associated pneumonia: A nationwide retrospective cohort study

Journal of Hospital Medicine, EarlyView.
Abstract Background Nursing and healthcare‐associated pneumonia (NHCAP) is defined as pneumonia occurring in individuals with frequent healthcare contact, such as residents of care facilities or patients with impaired activities of daily living. The effectiveness of broad‐spectrum antibiotics in treating NHCAP remains unclear.
